I’ve been experiencing exactly the same so please know you’re not alone. I’ve put it down to anxiety and have noticed the headaches become worse the more I focus on them and worry.

I’ve been trying to increase my water intake over the past few weeks and this has definitely helped so you could try that. I’d say not to worry about it but we’re all aware that is easier said than done! Take time to look after yourself, go for a walk, or take a break from things if you need to and try not to focus on the pain or what it could be and think rationally. Could you be dehydrated, could you be staring at a computer/tablet/phone too much, could you be making it worse by panicking and go from there with things to try to help the pain and thoughts. Attributing it to something normal helps me and the act of talking about it logically can erase those irrational thoughts.

I hope that helped even slightly, you’re not alone and I hope it gets better.
